On Monday, Nalim made a journey.
xenn [34]

Answer:

Step-by-step explanation:

Let's put in some numbers to make this easier to understand.

Let's say she has to travel 20 km.

On Monday, she travels at 4 kph.  This takes 5 hours.

On Tuesday she travels 25% faster, at 5 kph.  This takes 4 hours.  

To figure percent reduction we take

100 % * (old - new) / old  

100 % * (5 hr - 4 hr ) / 5 hr

100 % * 1 hr / 5 hr

100 % * 0.20

20% reduction.
